An injection molded product may include a corner shingle resembling a single course of tiles that differ in size. The corner shingle may be a semi-crystalline thermoplastic and having a wood grain direction. Streaks may be formed in the corner shingle that are substantially parallel to the wood grain direction. The streaks may extend through an interior of the corner shingle and appear as contrasting streaks on an exterior of the corner shingle to form a variegated wood grain appearance. In addition, an injection molded vestige may be formed in the corner shingle. The injection molded vestige may be located adjacent a perimeter of the corner shingle, and may comprise the location at which material entered an injection mold through a gate.

A corner siding product may include a plurality of panels. Each panel may include a front face with a simulated pattern and an inner wall formed along a perimeter of the panel. The corner siding product may further include a clip that is configured engage each panel to hold the panels together and form a corner.

An improved architectural trim device constructed from cellular polyvinylchloride. The process employs manufacturing dimensionalized cellular PVC architectural components from a single sheet of plastic that can achieve both linear and radius shapes without using heat bending techniques. The process strengthens the cellular PVC, giving it more structural integrity than other products made strictly of cellular PVC. These techniques enable the manufacture of components with tighter tolerances than traditional heat bending techniques which distort the size and shape of the material making accurate and precise assembly difficult.

A prefabricated decorative quoin system includes an elongated edge column attachable to an existing wall corner. The elongated edge column may be formed by a plurality of elongated edge members interconnected end-to-end. A plurality of prefabricated quoin panels are attached to the edge column in vertical stacked relation. A lighting array disposed relative to an inner surface of the quoin panels may be used to illuminate the quoin panels.
